Las Vegas gunman shot security guard before massacre

Here's what we learned about the investigation and the questions that remain unanswered in the deadliest mass shooting in modern U.S. history.

Lombardo said that Campos was shot at 9:59 p.m. after heading to the 32nd floor in response to an alarm reporting an open door to another room. Six minutes later, Paddock began firing into the crowd at the Route 91 Harvest Festival, authorities said.

The search came exactly a week after Paddock opened fire on a country music crowd, killing 58 and injuring almost 500.

Last week, police said Paddock had shot at concert-goers for 10 minutes and stopped firing around 10:15 p.m.

The home was first searched Monday by Las Vegas police, who said they found 19 guns and several pounds of potentially explosive materials at the house that Paddock bought in early 2015.

"What we have learned is that Mr. Campos was encountered by the suspect prior to his shooting", Lombardo told the crowd.

"In close proximity of Mr. Campos being shot there was also a maintenance worker on the 32nd floor". Why did it take officers 18 minutes from that point to reach the gunman's floor? Police have also warned that information released to the public could change as the investigation continues, and Lombardo said that this is what happened with the timeline involving the guard, Jesus Campos.

Officers who stormed Paddock's room said they found an "armory" of guns and ammunition inside - along with a note suggesting the gunman had mapped out the trajectory of the bullets he would rain down on concertgoers. He notifies hotel security, according to Lombardo. His assumption was that Paddock meant to place either a camera or a rifle there, but the drilling was not completed, Lombardo said.

"I would not make that assumption" about speeding up the timeline. "I'm not privy to that".

"The police, once the attack starts, dispatch is drowning in this information, you hear all these reports of gunshots going on and the confusion about what is going on is very, very common". And why did he stop shooting? He said the door was not Paddock's, but did not elaborate. "Because this individual purposefully hid his actions leading up to this event and it is hard for us to find answers for those actions".

Investigators are still piecing together evidence left behind in the hotel room and probing Paddock's background to determine why the retired accountant committed the worst mass shooting in modern USA history.

"As I've said from day one, we want to figure out the why to this and we'd like to know the motive".

Lombardo said police and Federal Bureau of Investigation agents, including behavioral profilers, still haven't found a particular event in Paddock's life that might have triggered the shooting. Authorities have said that Paddock used devices called bump stocks to turn at least a dozen rifles into something akin to automatic weapons. "We believe he chose to take the lives he did and he had a very purposeful plan that he carried out". "We believe he chose to take the lives he did and he had a very purposeful plan that he carried out".

Eric Paddock told the Las Vegas Review-Journal that he plans to put his brother's assets in a trust that would benefit the shooting victims. He declined to discuss the interviews, but said each one was another piece in the puzzle in this case.

"I don't think they are after anything specific", Tanner told The Associated Press.

"I'm trying to get them to understand Steve's mindset", Paddock told the newspaper.

Police say he killed himself before they could get to him and that he looked like an "average Joe". Reports on Tuesday said about 200 bullets were fired into the Mandalay Bay hotel hallway in the volley that hit Campos.

So many phones, backpacks, lawn chairs and other items were left behind that the Federal Bureau of Investigation has divided the huge crime scene into four quadrants, releasing items from only one of them at a time, starting on Sunday, FBI Victims Services chief Paul Flood said.
